Question

When does an integrated circuit exhibit greater degree of freedom and electrical performance?

(a) In thin and thick film technology

(b) In semiconductor technology

(c) In semiconductor and films technology

(d) In thick film technology only

The question was asked by my school principal while I was bunking the class.

My question is taken from Thin Film and Thick Film Technology topic in portion IC Fabrication of Linear Integrated Circuits

Answer 1

The correct answer is:

(b) In semiconductor technology

Explanation:

Integrated circuits exhibit a greater degree of freedom and superior electrical performance when designed using semiconductor technology. This is because semiconductor technology allows for:

1. Miniaturization: The creation of compact, high-density circuits with precise control over electrical characteristics.
2. Versatility: The ability to fabricate transistors, diodes, capacitors, and other components directly on the semiconductor substrate.
3. Performance: Lower parasitic effects, higher speed, and better thermal stability compared to thick or thin film technologies.

Why not the other options?

• (a) In thin and thick film technology: These are mainly used for passive components or hybrid circuits, not for achieving high-performance active components.
• (c) In semiconductor and films technology: While combining both technologies can offer benefits, the standalone semiconductor technology provides the highest electrical performance.
• (d) In thick film technology only: Thick films are limited in performance and primarily used for specific applications requiring higher current or ruggedness, but not for high electrical performance.
